NATA Supplement Guidelines 2026: A Department Checklist

The NATA supplement guidelines at a glance

What does the 2026 NATA statement say?

It starts from how common supplements are. About 40 percent of recreational athletes in the United States report using them. Up to 100 percent of elite and professional athletes worldwide do.

It also starts from how lightly supplements are regulated. They do not need FDA approval before they are sold. The FDA can act against a bad product only after it reaches the market.

That puts the athletic trainer in a specific spot. In many cases, the athletic trainer is the first health care professional asked to review a supplement an athlete already takes. The trainer is asked about its safety, its effectiveness and whether it is legal.

The statement aims to give that person tools. It also makes clear when to refer the athlete to a sports registered dietitian, a dietitian who works in sport. The trainer should consult reliable resources along the way.

Three ideas run through the whole document:

• Food first, but not always food only. Diet and fueling come first. Sometimes a supplement is in the athlete's interest, such as for a deficiency that food cannot easily fix.
• Keep the conversation open. The statement does not tell trainers to advise against all supplements. It tells them to ask why the athlete wants the product.
• The athlete carries the risk. Athletes take on the risk of anything they swallow. The athletic trainer should be ready to help judge whether it is safe, effective and legal.

What are the three questions?

Every supplement gets the same three questions. Here is how the recommendations below fit each one. The grouping is ours.

• Is it safe? Supplements can be contaminated, meaning something is in the product that should not be there. The statement also advises against intakes above the tolerable upper intake level, a limit set by the National Institutes of Health. Going over it can cause side effects or toxic responses.
• Is it effective? Only a short list of products has enough evidence to grade.
• Is it legal for the sport? Check the right banned list. The athlete is responsible for what is in their sample.

The statement and NATA's course on it name the same risks: contamination, mislabeling and banned substances. Mislabeling means the label leaves out an ingredient or gets an amount wrong.

What are the 16 recommendations?

Each recommendation has an evidence grade from the Strength of Recommendation Taxonomy (SORT). A grade says how strong the research behind it is, and A is the strongest. The grouping below is ours. The numbers and grades are the statement's.

In third party testing, a company with no stake in the product tests it, to check that what is inside matches the label. Strict liability means athletes are responsible for anything in their sample, even if a product was contaminated. MedWatch is the FDA's program for reporting bad reactions to a product.

Recommendation 16 lists the short set of products the authors think are well enough studied to grade:

The statement says the list backed by substantial research is limited. For how the endurance items apply by event length, see our endurance supplements guide.

How should staff screen athletes?

The statement asks athletic trainers to ask about supplements often. It offers ten questions for the preparticipation physical, the exam before the season, and for follow up. In plain terms they cover:

• Which supplements the athlete takes now, with brand names and doses.
• Foods and drinks that act like supplements, such as energy drinks and electrolyte products.
• How and when each product is taken.
• Who recommended it, or where the athlete heard about it.
• Why they take it, and what effects, good or bad, they have noticed.
• Whether they would like to learn a lower risk way to supplement.

NATA's continuing education course teaches the same habit. It shows trainers how to use a structured screening process in preparticipation exams and athlete meetings. It also shows them how to tell higher risk from lower risk products using third party testing and regulatory tools.

What does third party testing settle?

The statement makes the case for third party testing, and it is careful about the limits:

• Third party testing "does not automatically mean the supplement is free of banned substances in sport". Many certifications check purity, such as heavy metals. A tested athlete needs banned substance screening.
• Programs differ in what they test for, how many batches they test and what else they audit.
• Athletes should keep the packaging or record the lot number of every product they use. A lot (or batch) is one production run.
• Certification should be tied to specific containers, batches or lots, so the athlete's own batch is covered.
• Education alone may not change behavior. Giving athletes suitable supplements through controlled channels has been shown to reduce anti-doping rule violations.

The statement names NSF, Informed Sport and BSCG among its examples of reputable programs that test for banned substances. It also names programs based in Europe and Australia. It draws the same line this site draws: Informed Sport tests each batch, while Informed Choice uses monthly spot testing.

Which products does the statement call high risk?

The statement does not recommend several groups of supplements. They have been linked again and again to products that were tampered with or contaminated with banned substances:

• Muscle building or weight gainer formulas and amino acid blends
• Thermogenic fat burners, products sold to burn fat by raising body heat
• Testosterone boosters and stimulant botanicals (plant products that act like stimulants, which speed up the body)
• Multicomponent herbal preparations
• Proprietary pre workout blends

A proprietary blend lists its ingredients but hides the amount of each one. The statement warns about these blends in general, because the hidden amounts make it hard to judge their safety, their effect or whether they break the rules.

Where do NCAA rules add to the statement?

The statement is written for every setting, so it cannot carry each league's rules. A Division I department has two more layers.

• What a school may provide. NCAA Bylaw 16.5.2.7 limits it to six classes of supplements that contain no NCAA banned substances.
• The NCAA banned list. The NCAA has its own list of banned substances.

So "supported by the NATA statement" and "something we can hand out" are different questions.

This table is our comparison of the two documents, not something either one prints. The bylaw is marked as an area of autonomy, so each Division I subdivision may change it. Your compliance office has the final word. For the full banned list by class, see our NCAA banned substances guide.

What should a department do?

This is our reading of the statement, turned into steps. NATA has not reviewed or endorsed it.

1. Write one shared supplement policy. When several health professionals work with the same athlete, they should follow a shared supplement policy or guidelines.
2. Screen at the preparticipation physical, then keep asking. Use the ten questions, and ask again through the year, because what athletes take changes.
3. Record brand, product, dose and lot. A product name alone is not enough to check a certification or act on a recall.
4. Ask the three questions about every product. Is it safe, effective and legal for this sport?
5. Check certification for the athlete's lot. Not just the brand, and not just a purity seal.
6. Sort out the high risk groups. Fat burners, testosterone boosters, proprietary pre workout blends and the rest of the list above get a harder look.
7. Check the right banned list. For NCAA sports, that is the NCAA list. The statement lists Drug Free Sport AXIS among its resources.
8. Set the referral path. Decide who the sports registered dietitian is, and what triggers a referral. Examples are a suspected deficiency, disordered eating or an interaction with a medication.
9. Teach strict liability. Athletes are responsible for what is in their sample, even from a contaminated product.
10. Report adverse events. An adverse event is a bad reaction. The statement points athletes to the FDA's MedWatch program.
11. Use controlled channels where the rules allow. What the department provides must fit the six classes the NCAA allows.

Who do athletes actually ask about supplements?

It depends on staffing. The statement cites research on where athletes get supplement information. Sports dietitians were the main source far less often in Division III (8.8 percent) than in Division I (58.1 percent). Athletic trainers most often filled the gap.

A department without a full time sports dietitian is where the athletic trainer's process matters most.

Does the statement apply to high school athletes?

Only with caution. Its recommendations reflect studies in adults, and advice for children and teens may differ.

Many developing athletes do not need performance supplements. Good fueling and a food first approach already support their growth and training. In a high school sample the statement cites, parents were the most common influence on supplement use, ahead of athletic trainers and dietitians.

This article gives no doses. A high school athlete should talk to a doctor, athletic trainer or registered dietitian before starting any supplement.

Check a supplement with Varsity Stack

The hard part of the statement is not the principles. It is knowing what each athlete takes, from which lot, and what staff already said about it, across a whole roster.

For athletes: scan the barcode or take a photo of the label in the free Varsity Stack app. It checks the product against our certification database before you buy. Then add it to your stack, so you and your staff know what you take.

Download the App

For coaches, sports dietitians and athletic trainers: the team dashboard shows every athlete's stack and whether each product is certified, so staff can review what athletes take. Staff can also record the lot numbers of the products athletes hold, and see which athletes hold a recalled lot.

Varsity Stack does not replace the judgment of an athletic trainer or a sports dietitian.

Varsity Stack does not laboratory test supplements, and certification lowers risk without removing it.
